Oil burn cloud on engine deceleration

$129!!! It better come with a +5hp sticker for that much.

I just finished a successful test run with no smoke on downhill deceleration. I pulled the PCV from the valve cover and kept it connected to the carb and then put my extra breather on the open valve cover port. This gave me the same air mixture as prior but removed the possibility of oil being sucked through the PCV.

So, I believe this identifies the PCV as the culprit here.

Just remember that PCV actually helps promote ring seal. You have a dilemma, go buy 10 different valves and experiment or drop some cash for something you can actually adjust to meet your needs.

What covers do you have and can you use a factory resto piece? Still seems you have and inadequate baffle setup. Glad you have your finger on it and sure you will make the best decision for your needs. You have shown great troubleshooting skills in your diagnosis!
